COMBINATION DESK-CHAIR.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed December 27, 1916. Serial No. 139,167.

To all whom it may concern:

Be it known that I, JACOB W. LATTIG, a citizen of the United States, residing at Bethlehem, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Combination Desk-Chairs, of which the following is a specification.

My invention consists of an improved type of combination desk chair, which is particularly serviceable in restaurants, schools, or other places where a table or desk is required to be near the occupant of the chair. One of the objects of my invention is to provide a chair of the above described type which will be of simple and durable construction, and in which the table or desk portion may be easily and quickly moved out of the way of the occupant of the chair, or

moved into different positions to suit the convenience of said occupant.

This object, and other advantageous ends, which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a side elevation of my improved chai'r.

Figs. 2 and 3 are respectively front elevation and plan views of Fig. 1.

Figs. 4 and 5 are fragmentary elevations of certain of the important features of my invention showin different possible positions thereof, an drawn on a larger scale than the previously mentioned figures.

Fig. 6 1s a sectional elevation taken on the line ac Fig. 4, and

Fig. 7 is a fragmentary view lo'okin in the direction of the arrow X Fi 2 w en the table or desk is in a raised position.

Referring to the drawings, the chair 1 comprises members 2 and 3 which form the rear legs and a support for a back rest 4.

Front legs 5 and 6 are connected by bot tom rails 7 and 8 adjacent the lower portion thereof, and said front leg 5 and rear leg 2 are connected by a top rail 9 which may be used as an arm rest. V

A seat 10 is supported by intermediate side rails 11 and 12, said intermediate rails being respectively connected to a standard 13 and ,to the front leg 6. The spaces between the standard 13 and front leg 6, and between the rear legs 2 and 3, are closed by panels 14 and 15 respectivley, and these panels, to-

gether with the seat 10, provide a chamber for a drawer'16 which may be used for the storage of any articles desired, and is provided with a handle 17 by which the drawer can readily be operated.

The standard 13 and the front leg 5 are preferably made tubular for the slidable reception of two desk supporting rods 18 and 19, and are provided with tapped openings for the reception of adjusting or wing nuts 20 and 21.

The adjusting rods 18 and 19 are preferably made of different lengths as clearly shown in Fig. 1, and said rod 18 has directly pivotally connected to it at 22 adjacent its upper end a plate 22 which is provided with a longitudinally extending groove or recess 23, and at one end has a slot 24, the function of which will be described hereinafter.

Alink 25 is pivoted to the plate 22, and a bolt 26 pivotally connects said link to the upper portion of the rod 19, said bolt in the present instance extending from the link through the slot and into said rod 19. As clearly shown in Figs. 2 and 6, the plate 22 is located on the outside of the said rods'18 and 19 and in such manner that the upper ends of said rods 18 and 19 extend across the groove 23 in said plate.

The table or desk 1 may be made of any suitable material, and if desired, provided with a groove 27 for the reception of pencils or other articles. This desk has. normally depending supporting plates28"and 29, between which extend bars 30 and 31, the latter being secured within said depending plates, and in such position that the bar 30 will fit within the groove 23, and the bar 31 will abut the inner portion of the rods 18 and 19 at a different level than the bar 30, so that the bars 30 and 31 in normal position as clearly shown in Fig. 6, will jam the rods 18 and 19.

Thebar 30 ismade cylindrical, and the recess or groove'23 is made to conform to the contour of this bar, so that the latter may pivot within said groove when the table is raised into the position shown in Fig. 7.

In addition, the bar30 is made lon r than the length of the groove 23, so that t e table may be moved toward or away from the back of the chair, Fig. 1 showing the table in two positions rendered possible by this construction.

By having the plate 22 provided with the slot 243.5 previously described, it is possible merely by raising or lowering the rod 19 to tilt the table at any desired angle since the plate 22 will rock on the pivot 22 and the link 25 will also move to accommodate the required movement, the slot 24 permitting a relative movement between the bolt 26 and the pivot 22.

By the construction of the grooved plate 22 and the members cooperating therewith as previously described, it will beseen that it is impossible while the rods 18 and 19 are within their respective securing members, for the table to be accidentally detached since the bar 30 at all times is confined between the plate 22 and the upper end of the rod 19. This is a particular advantage since it prevents the malicious or accidental removal of the table or desk portion of t chair. Also, even though the table is abruptly thrown or turned upwardly, the construction is such as to resist such movement without the breakin of the several parts.

%urthermore, in a chair constructed after my invention, the overhanging portion of the table tends to securely bind the latter in position, so that the bar 30 will not readily slide within the grooved plate even though the table is tilted.

To remove the table from the chair, it is necessary in the construction shown to lift either the rod 18 or 19 out of its secured position and to move the several parts until the rods 18 and 19 are parallel with the direction of the groove 23. This is necessary in order to move the upper ends of said rods away from the groove 23, it being readily understood that after said rods have been moved from the bar 30, the latter may freely he slid out of the groove 23.

As an additional reinforcement for the front leg 5, I rovide a bracket arm 32 which extends rom said leg 'to a bottom front rail 33, the latter connecting the front leg 6 with the standard 13.

When the table is turned into the position as shown in Fig. 7, so as to be out of the way of the occupant of the chair, the edge 34 of said table will rest against the rods 18 and 19, thereby (providing a stop.

Having thus describe my invention, what I claim as new and desire to secure by Let-,

ters Patent is: l
